Accounting for Service-Type Warranty and Warranty Expense/Obligation

ree

Warranties are common in product sales, offering buyers protection against defects or failures. From an accounting perspective, warranties are classified based on the type of coverage provided — with significantly different recognition, timing, and presentation requirements.


Under U.S. GAAP, warranties are categorized into:

✦ Assurance-type warranties, which guarantee that a product will function as promised;

✦ Service-type warranties, which provide an additional service beyond the product’s basic functionality


These categories determine whether a liability or a revenue deferral is recognized, and when expenses and revenue are recorded. This article explains the accounting for both types, with emphasis on warranty obligations and service revenue recognition.


1. Assurance-Type Warranties (Standard Warranties)

Definition:

An assurance-type warranty provides customers with standard protection against defects that existed at the time of sale. It is not separately priced and is included in the sale price of the product.


Accounting Treatment (ASC 460):

  • Recognize a warranty liability at the time of sale

  • Estimate the cost to satisfy future claims

  • Record warranty expense in the same period as the related sale

  • Use historical claim data to estimate costs


Example – Initial Recognition

A company sells a product for $10,000 and estimates future warranty costs at $500.

Debit: Warranty Expense – $500
Credit: Warranty Liability – $500

_________

Debit: Cash (or Accounts Receivable) – $10,000
Credit: Sales Revenue – $10,000

When a Claim Is Fulfilled

If the company incurs $400 of actual repair costs:

Debit: Warranty Liability – $400
Credit: Inventory (or Cash) – $400

2. Service-Type Warranties (Extended Warranties)


Definition:

A service-type warranty is sold separately and provides additional coverage or services beyond the standard assurance warranty period.

These are considered separate performance obligations under ASC 606.


Accounting Treatment (ASC 606):

  • Recognize deferred revenue at the time of warranty sale

  • Revenue is recognized over the period the warranty covers

  • Use straight-line or usage-based methods, unless another pattern better reflects the service


Example – At Warranty Sale

A customer buys a 2-year extended warranty for $600.

Debit: Cash – $600
Credit: Deferred Revenue – $600

Monthly Revenue Recognition (Straight-Line)

Revenue is recognized evenly over 24 months ($25/month):

Debit: Deferred Revenue – $25
Credit: Warranty Revenue – $25

When a Claim Is Fulfilled

If the company incurs $90 in repair costs under the extended warranty:

Debit: Warranty Expense – $90
Credit: Inventory (or Cash) – $90

4. Numerical Comparison Example

Scenario:

  • A company sells a laptop for $1,000.

  • Standard warranty: 1 year, estimated repair cost = $30

  • Extended warranty: 2 years, sold separately for $120


At Time of Sale:

Debit: Cash – $1,120
Credit: Sales Revenue – $1,000
Credit: Deferred Revenue – $120

_________

Debit: Warranty Expense – $30
Credit: Warranty Liability – $30

Monthly Revenue Recognition (Service Warranty)

Debit: Deferred Revenue – $5
Credit: Warranty Revenue – $5

When a Warranty Claim Is Settled (Standard Warranty)

Assuming a $25 repair:

Debit: Warranty Liability – $25
Credit: Inventory (or Cash) – $25

5. Disclosure Requirements

Companies must disclose:

  • The nature and terms of warranties offered

  • The method used to estimate warranty liabilities

  • Changes in the carrying amount of warranty obligations:

    • Beginning balance

    • Additions from new sales

    • Deductions for actual costs

    • Adjustments for changes in estimates

These are typically included in the notes to the financial statements.


6. Financial Reporting Impacts

  • Matching Principle: Assurance warranty expense is matched to the period of sale; service warranty revenue is matched to the period of service.

  • Revenue Deferral: Extended warranty revenue smooths earnings over time.

  • Liability Management: Accurately estimating warranty obligations avoids over/understatement of liabilities.

  • Ratio Analysis: Differing warranty types impact gross margin, operating income, and current liabilities.
